iExcell 25 Pcs Black Ethernet Hub Port RJ45 Anti Dust Cover Cap Protector Plug

these are great rj45 port dust covers. they dont get stuck on the wires if accidentally pushed too far in, and easy to remove.

Used to seal connectors on an industrial computer

These fit snugly and stay in place. Very nice. It would be nice if they had other colors - such as red. Since they are all black you cannot easily see that an ethernet port has one in it. I use these because my product has two ethernet ports and I want my customers to use the left one first (they rarely need to use the second one). By putting one of these in the right one it prevents them from plugging their network cable into it. Unfortunately they still try because it is black and you cant easily tell its a rubber plug. A red one would solve this problem. Still - this is a good item and I highly recommend it. There are others out there, but the other one I tried will just fall out under its own weight.

Easy rubber nubbings to plug your unused ethernet ports to prevent dust from screwing them up.

These work great! Now I need more Ethernet ports to fill with the extras I have, lol...

Works good as it should.

These are great little plugs, Im using them to cover up currently unused network ports in my switch and gateway. They fit snug and seem well made and I believe theyll last as long as I need them to. I feel like $10 for 50 of them is a pretty good deal, thats only twenty cents each! If you have a lot of ports you want to protect, this is the way to go.

Nothing special, but works as expected.

Does a great job keeping dust out of the inactive Jacks.

Used these to cover the open ports of my switch. Easy to put in and take out.
